Flight attendants and pilots face the greatest risk of radiation-related cancer deaths, surpassing individuals working directly with radioactive substances, as per a recent study. Cosmic radiation, originating from space, is more intense at higher altitudes where individuals flying are exposed to it.
Previous small-scale studies have hinted at increased cancer mortality rates among frequent fliers, especially pilots and flight attendants. The latest study, published by JAMA Internal Medicine, examined over 12 million death certificates containing occupational data. It assessed cancer death rates linked to radiation exposure, such as leukemia, lymphoma, multiple myeloma, and various other cancers.
Among more than 500 occupations analyzed, flight attendants exhibited the highest fatality rates from radiation-related cancers, with pilots ranking second. The study suggested that both groups had significantly elevated risks for each type of radiation-associated cancer but did not show higher-than-average death rates from non-radiation-related cancers.
The study challenged the common belief that flight crews’ increased skin cancer risk stems from sunny layovers. Instead, tighter schedules and cockpit exposures were highlighted as potential contributors. Flight attendants had a 50% higher likelihood of succumbing to radiation-linked cancers compared to the general workforce, while pilots had a 36% higher risk.
Despite some study limitations, such as the inability to quantify specific sources of exposure for each crew member, the research emphasized the challenge of delineating the impact of multiple concurrent exposures like cosmic radiation, UV-A light, and circadian disruptions.
The report underscored the lack of federal regulations on monitoring radiation exposure for aircrews and emphasized the need for heightened awareness and preventive measures. Recommendations included regular skin screenings for high-altitude workers, earlier or more frequent mammograms for female crew members, and a vigilant approach to cancer detection among pilots and flight attendants.
In conclusion, the study sheds light on the occupational hazards faced by flight crews, urging increased awareness, monitoring, and precautionary measures to mitigate the risks associated with radiation exposure in the aviation industry.
